This is Episode 35 of the show! Today we bring you meatless meat for carnivores, getting energy from where the sun don’t shine, eyes in the back of your head, and whether or not humans should go to Mars.
PresentMeat-Eaters, Meet your Non-meat meat!
- Plant based ground beef alternativeDeveloped by “Impossible Foods”Founded by a Stanford biochemist Patrick BrownThis isn’t a just a pseudo-meat for vegetarians and vegans, eitherTarget market is hardcore carnivoresWe’ve discussed a few times about the amount of water, electricity, and other resources required to meet the global demand for meatThis product requires far less resources, has a drastically shorter time-to-table and should become price competitive in the near future - hopefully even becoming cheaper than the real dealApparently, if the article is to believed, the taste is incredible
- The author noted that it was a bit less flavorful than real beef, but had he not known that it wasn’t meat, he wouldn’t have noticed.
- Heme is an iron-containing molecule in blood that carries oxygenLegumes contain leghemoglobin which could have been used… buuuut…Extracting that is expensive, time consuming and still unearths carbon, which is one of the main goals of finding an alternative product
- They took the gene responsible for producing heme from the soybean and added it to yeastNow they can make vats of the magic ingredientOne vat is enough to make 20,000 1/4lb (~110g) patties!!
- Using gas chromatography mass spectrometryCooked meat gases were analyzedDozens of scents combine to smell like meat, which have been replicated
- More proteinLess fatFewer caloriesNo cholesterolNo animals were harmed in the making of this burger (religious & ethical objections quelled)
- Brown calls the “Beyond Burger” a “home run” and sees plenty of room in the market for both of these players - with Beyond Burger targeting grocery stores first and Impossible Foods going for restaurant chains first.
Pearl Auto Retrofits Your Car with a Rearview Camera
- Pearl Auto is a bunch of ex-Apple people, apparently. I hope that means their products look great, are easy to use, and cost a fortune.RearVision claims to be “the backup camera redefined.”ORLY? How do you redefine what is in effect a straightforward service? A camera shows you what’s behind you. Seems straightforward enough.Hard to call this “redefinition.” More like...a little complicated, but well-thought out.
- Mounts to the license plate. There’s a bracket that goes through the screw holes. Then the unit mounts to the bracket. Secure, will be okay for most, but a little yuck for me.Has 2 cameras. One’s a wide angle, one’s a more typical view. Both HD. At least, that’s the way the demos look. Tech notes say one is optimized for daytime, and the other is IR and optimized for night. Also a solar charger.Car adapter plugs into the OBD-II port. Hope you weren’t using it for anything else. So plate camera system to adapter, wirelessly. Adapter to phone app, wirelessly. But it’s more than just a wireless relay sucking power from the OBD port. “Through advanced image processing, it analyzes the video streams to detect obstacles in your path, providing audible alerts and sending visual alerts to your phone.” Seems it offloads some compute of the imaging system in the back.Wireless from there to a phone app, where in the demo you see a split screen. One camera view on top, another on bottom. Or see all from one camera in landscape mode.Comes with a magnetic phone mount.
- "Any iPhone® 5 (or newer) with iOS 9 (or newer) OR Select Android™ phones with Bluetooth® 4.0 and Lollipop 5.0 (or newer)"Theft deterrent screw. Because getting those bits is hard.
Renewables can’t produce enough off-peak power to meet demand… or can they?
- Coal, Gas, and Nuclear are pervasive and reliableWind and Solar are catching up, but in the US there is a persistent idea that they cannot meet more than 15-20% of the grid’s demandThis article argues that this isn’t strictly truePortugal recently ran for several days off 100% wind, solar, and hydro power
- This is obviously a very different use case than the US
- SolarWindHydro-power bridging the gap - it’s not ubiquitous, but it always generates power, assuming the river hasn’t been dammed or diverted somehow
- Do nothing - I’ll “manage” my demand myselfBe notified - I can manage my demand in response to notificationsUtility control - They control the water heater, etc. remotely.
Should humans go to Mars?

- FOR.
- Fulfillment of a fantasy.We humans are curious.Progress - a technological achievement.Earth’s support for humans long-term is in question. (Climate change, rising oceans, etc.)Water under the Martian surface is quite helpful.Because not the moon.
- No atmosphere.Wild temperature fluctuations.No protection from solar radiation.Moon dust would be like “tiny shards of glass.”
- A decent chance that the trip will kill you.It’s FAR. 225 million kilometers on average. Closest approach to Earth back in 2003 put it about 56 million Km.We’re bad at efficient propulsion systems.Mars is not terribly hospitable to human life.
- Very little atmosphere - 100 times thinner than that of Earth’s, and made of mostly carbon dioxide with just a smidge of nitrogen.Toxic - salt compound perchlorate in the ground.

Apollo 13 was terrible, Hollywood tripe.
Ron Howard stated that, after the first test preview of the film, one of the comment cards indicated "total disdain"; the audience member had written that it was a "typical Hollywood" ending and that the crew would never have survived.
